PROBLEM TO BE SOLVED: To obtain a bearing oil composition which is excellent in wear resistance and oxidation stability. SOLUTION: This bearing oil composition is prepared by dissolving a nonionic surfactant such as a polyoxyalkylene glycol or its ether or ester and an anti-wear agent such as a fatty acid ester (optionally containing a partial ester) of neopentyl glycol, trimethylol propane or pentaerithritol, a phosphate, a phosphite, an acid phosphate or an amine salt of an acid phosphate in a base oil.
